I'm thinking about getting a multi stage or variable speed furnace to go with my fairly new 10 Seer Carrier condensor. Will the AC air handler fan speed be set to a fixed speed because the coil could ice up? Will I only get the benefits of multi speed fan for the heating part? Or maybe, because of the condensor, have to set it to fixed speed for both functions (and therefore should get a single speed furnace)? hmmm Just asking so I don't sound foolish before I talk to the contractors tomorrow. :)
